TORSION-ROD FASTENING.

Specification of Letters Patent.

Fatented Dec. 22, 1914.

To all whom it may concern Be it known that I, BELVIN T. VVILLIs'roN, a citizen of the United States, and resident of Somerville, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Torsion- Rod Fastenings, of which the following is a specification.

torsion rod; and Fig. 3 is an end view of the torsion rod.

In Fig. 1 two precisely similar socket members designated by S are shown asjointed together to form a universal joint. Each of these socket members is provided with a polygonal, for instance, a square opening in 1 its end, said opening being ada ted to receive and hold the polygonal en R of the torsion rod B. Each of the socket members is slotted as at S so as to enable the binding bolt B to pinch the sides of the polygonal opening against the correspondingly polygonal end R of the torsion rod R. The binding bolt B passes across the slot S and intersects the polygonal opening, preferably crossing one of the internal dihedral angles of the said opening.

The torsion rod R has its ends squared as at R (see Fig. 2) and this squared end is peripherally grooved as at R so as to form a number of notches in the edges of the polygonal end, this being shown as a squared end in the figures. This squared end B fits a similarly squared opening in the socket member S, and one of the notches R is engaged by the binding bolt B, so that While the pinch produced by the binding bolt B holds the torsion rod securely against rattling the rod is further positively held against longitudinal slipping in the socket by the bolt B which thus performs the two functions of a binding bolt and a key or dutchman. The binding bolt B is preferably a screw bolt engaging a nut B. The

bolt may project through the nut B and be perforated to receive a cotter pin C for the sake of complete security.

.While the intention is to maintain the junction between the rod R and the socket piece S firm and free from any play or backlash, nevertheless should the bolt B become loose for' any reason, the squared end of the rod R fitting its corresponding opening in the socket piece S will enable the rod to perform its function as a torsion rod, while the engagement of the bolt B with a notch R will effectually prevent the rod R from slipping longitudinally. If for any reason it be desired to change the adjustment of the torsion rod R, this can be done by withdrawing the bolt B and the rod R, turning the lattera quarter turn and replacing it in the opening, when another of the notches R will be in place to engage the bolt B when the latter is inserted. What I claim and desire to secure by Letters Patent is:

nation of a torsion rod regularly polygonal at its end, said polygonal end provided with a plurality of peripheral notches corresponding in number with the plurality of sides of said end, a socket member with a cone sponding'regular polygonal opening, said socket member being slotted at one side of its opening, and a binding bolt crossing the slot and intersecting the polygonal opening, and adapted to engage any of the peripheral notches in the end.
